Description

Technical Field

[0001] The utility model relates to the technical field of seedling hydroponics, in particular to a Masson pine seedling hydroponics device. Background Art

[0002] Masson pine has a wide range of uses. It is an excellent raw material for papermaking. It has the economic properties of fast growth and high yield. It has a wide range of uses. Pine wood is an important material for industrial and agricultural production. It is mainly used for construction, sleepers, mine pillars, board making, packaging boxes, matchsticks, plywood, etc. The wood is extremely resistant to water and moisture. It is said to be "a thousand-year-old pine in the water", and is particularly suitable for underwater engineering. The wood contains 62% fiber. After degreasing, it is an important raw material for papermaking and artificial fiber industry. Masson pine is also China's main resin-producing tree species. Rosin is an important raw material for many light and heavy industries, mainly used in papermaking, rubber, coatings, paints, adhesives and other industries. Turpentine can be synthesized into pine oil, processed into resins, synthesized into spices, produced into pesticides, and is a synthetic raw material for many precious terpene spices. Pine needles contain 0.2% to 0.5% of volatile oil, which can be extracted from pine needle oil for use as cooling sprays, soap essences and preparation of other synthetic spices. Tannin can also be extracted. Bark can be used to make adhesives and artificial boards. Pine seeds contain 30% oil. In addition to being edible, they can also be used to make soap, paint, and lubricants. Pine cones can be used to extract crude oil. Pine roots can be used to extract pine tar, and can also be used to cultivate the valuable Chinese medicinal material - Poria cocos. Pollen can be used as medicine. Pine branches are rich in rosin and have strong firepower. They are the favorite firewood for kiln burning. Pine soot ink and dyes can also be extracted. Because the wood fiber is long, it is the most important raw material for papermaking and artificial fiberboard.

[0003] When hydroponically cultivating Masson pine seedlings, existing hydroponic devices mostly use circulating nutrient solution to hydroponically cultivate the seedling roots. This hydroponic method will cause hypoxia in the seedling root environment, and the roots cannot breathe oxygen, thereby affecting the normal growth of the seedlings and reducing the success rate of hydroponics.
